1 Claim.

This invention relates to telephone booths and more particularly to that type of telephone booth known as stall.

In connection with the use of telephone booths it has been found that in certain premises the installation of such booths, either singly or in combination, is rendered dicult and sometimes impracticable due to the geometrical formation of the limited wall and floor space available in such premises.

This invention provides a telephone stall of basic construction with standard walls and shelf element extensions whereby the basic telephone stall may be readily converted to t against Walls of different geometric formations either singly or in a plurality of telephone stall combinations and which will be simple in construction, cheap to manufacture, efficient and convenient in use, and which provides eflicient securing means for holding the standard parts in assembled relation to each other.

In the drawing:

Fig, 1 is a perspective view of the telephone stall of the invention shown with extension elements on each side of the writing shelf and on each side of the backboard mounting;

Fig. 2 is an exploded View of Fig. 1, showing the means for securing standard removable parts in assembled relation to each other;

Fig. 3 is a view shown in vertical section taken on line 3-3 of Fig. 1; and

Fig. 4 is a view shown in vertical section taken on line 4-4 of Fig. 3.

According to the telephone stall of this invention, a mounting board M, Figs. 1 and 2, for the telephone apparatus is secured to a shelf S at right angles thereto by a number of ordinary Wood screws as WS, best seen in Fig. 2. The shelf S is in the form of a rectangularly-shaped wall board to the underside of which are secured as by a number of screws SS adjacent its longitudinal edges the parallelly disposed side wall board elements bl and b2 While a rear wall board element b4 which is secured to the mounting M by a screw SS forms in cooperation with the wall board element b3 the shelf S and the side wall elements bl and b2, a casing for housing a telephone directory, not shown. The board element. b3 has its front edge'extending a small distance beyond the front edge of shelf S to serve for supporting the opposite end of the telephone directory while being placed in or withdrawn from the casing thus formed.

The telephone stall construction as shown in Fig. 1 is adapted to be secured to the wall of a premises or mounted on a support or stand not shown, such support in turn being adapted to be secured to the floor of the premises as in any well-known manner.

As shown in Figs. 1 and 2 the shelf S is extended on both sides thereof by spacer boards bB which may be of any desired width secured in assembled relation to similar backboard spacer members b9 by a number of screws sc While the spacers bt and b9 are held in assembled angular relation to each other by a number of bolts Sd best seen in Fig. 2 passing through clearance holes in the Wall boards W, WI and in clearance holes in the shelf and backboard mounting extensions on each side of the backboard mounting M and shelf S, themselves forming a so-called basic stall and engaging nuts as ntl best seen in Figs. 3 and 4 placed in the recesses rc in the backboard mounting M and in shelf S, the side walls W, WI being interchangeable With the extension boards b8 and b9 from right to left of the stall and serving for holding the backboard and the shelf extensions in angular relation t0 each other and thereby the backboard mounting M and the shelf S in angular relation relative to each other.

The casing for the telephone directory is formed as above described by the combination of Wall boards bl, b2, b3 and b4 secured to the underside of shelf S as by a plurality of wood screws ss passing through clearance holes in the board b3 and transverse of the side Wall boards bl, b2 and rear wall board b4, best seen in Fig. 2, while the wall boards bl, b2 and rear Wall board b4 are secured to the board b3 of the telephone directory casing by a number of similar screws ds shown in Figs. 1 and 2.

It is understood that many other combinations of stalls may be effected by the use of the standard parts above described and this without de-l parting from the scope of the appended claim.

What is claimed is:

A telephone stall comprising a backboard mounting for a telephone apparatus, a shelf element secured to said backboard mounting in telephone directory, backboard mounting extensions and shelf extensions constructed to register with the opposite edges of said backboard mounting and the opposite edges of said shelf element, side wall elements constructed to register with the outer edges of said shelf extensions and outer edges of said mounting extensions, and a plurality of bolts extending through respective side wall elements, through respective extensions and partially through said backboard mountingand :shelf at respective edges thereof for collectively securing said` side .Wall elements, said shelf extensions and said mounting extensions to said backboard mounting and to said shelf, respectively.
